要score
使用逗号显示,您可以这样做:(注释在代码中)
var score:Number = 0;
var score_str:String;
var score_str_len:int;
Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;
Monster.addEventListener(TouchEvent.TOUCH_TAP, fl_TapHandler);
function fl_TapHandler(event:TouchEvent):void
{
score = score + 1;
score_str = score.toString();
score_str_len = score_str.length;
// here you can use score > 999 instead of score_str_len > 3
Taps_txt.text =
score_str_len > 3
// example : 1780
// score_str_len = 4
// score_str.substr(0, 4 - 3) = 1 : get thousands
// score_str.substr(4 - 3) = 780 : get the rest of our number : hundreds, tens and units
// => 1 + ',' + 780 = 1,780 : concatenate thousands + comma + (hundreds, tens and units)
? score_str.substr(0, score_str_len-3) + ',' + score_str.substr(score_str_len-3)
: score_str
;
// gives :
// score == 300 => 300
// score == 1285 => 1,285
// score == 87903 => 87,903
}
编辑 :
要支持大于 999.999 的数字,您可以这样做:
function fl_TapHandler(event:MouseEvent):void
{
score = score + 1;
score_str = score.toString();
Taps_txt.text = add_commas(score_str);
}
function add_commas(nb_str:String):String {
var tmp_str:String = '';
nb_str = nb_str.split('').reverse().join('');
for(var i = 0; i < nb_str.length; i++){
if(i > 0 && i % 3 == 0) tmp_str += ',';
tmp_str += nb_str.charAt(i);
}
return tmp_str.split('').reverse().join('');
/*
gives :
1234 => 1,234
12345 => 12,345
123456 => 123,456
1234567 => 1,234,567
12345678 => 12,345,678
123456789 => 123,456,789
1234567890 => 1,234,567,890
*/
}
希望能帮到你。
